Details of television displays the operators would need from the
remote cell were stated (e.g., views from the t;iree cameras on-board the
manipulator; from fixed, wall cameras; and.from a small, portable camera
held by the slave arm of the remote manipulator). Details of necessary
alphanumeric/graphic and hard-copy displays were also stated. For
example, operators would need information about the slave's position in
space, condition of its motors, and schematics of the equipment on which
it would be working. Remote sound information from the process cell, as
well as audio alarms and signals, were also considered.
Next, a list of all the control functions the operators would need
to perform the specified tasks was generated. First, all controls for
remote equipment were considered: controls for cameras, lights,3 tools,
transporter, and crane. Second, the controls necessary to present this
information to the operators were considered: monitor controls, video
switching, mixing, interaction with computer-generated graphic displays,
controls for remote sound, and emergency responses.
Since the control room must conform to the people who work there, a
list of personnel characteristics that would have to be accommodated was
generated. The list included operator reach and viewing envciopes for
5th percentile female to 95th percentile male,4 normal visual acuity,
and normal color vision.
All other accessories and equipment needed in the control room
(e.g, electronic racks, printers, storage for nonelectronic documents)
were listed. Information was also obtained on. the probable size and
shape of the room, and the location of doorways and ducts. Finally,
experience suggests that the operators be close enough to communicate
Here’s what’s next.
